Perhaps you should try some spelling variations:
optimization algorithms » optimisation algorithm, estimation algorithms, estimation algorithm
optimisation algorithms » optimisation algorithm, estimation algorithms, estimation algorithm
optimized algorithm » optimized algorithms, optimizer algorithms
qoe optimization » game optimization, _ optimization, stage optimization

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (( over ((optimized algorithm) or (optimisation algorithms)) ) or ( qoe optimization algorithms ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( over ((optimized algorithm) OR (optimisation algorithms)) ) OR ( qoe optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (( over ((optimized algorithm) or (optimisation algorithms)) ) or ( qoe optimization algorithms ))*.
